This module extends the debugger's 'f' command so that you can simply enter the standard module name to switch the debugger to it:
DB<1> fx My::Module
This would look for My::Module in %INC; if it was not found, we would attempt to 'use' the module. If this also fails, we give up, with an error message.
The standard subroutine name used by Devel::Command to denote a command implementation. YO do not need to call this routine; the debugger will do it for you at the appropriate time.
Returns 'fx' and a reference to the command implementation. This is a standard
part of Devel::Command's implementation, and serves to tell the debugger
how to resolve the 'fx' command.
Failed to load %s: %sWe tried to load the module you requested via 'use', but it failed. The error we received is shown.
Loaded %sWe successfully loaded the file and will witch to it.
Devel::Command::NewF requires that the .perldb (or perldb.ini, on Windows)
file contain a 'use' for Devel::Command.
